Fiat 2.5td cold start.

[Elmerthud]

Hi everyone I’m new to this site. But noticed on a early topic about cold start system on a Bosch pump. I own a hymer 1995 2.5td camper and I’m having problems with the cold start on the pump. Does anyone know about the advance enrichment device it has a wax stat but it seems to have 12v all the time should there be a relay for this to switch it off after a certain temp is reached. Many thanks to all in advance. Elmerthud. (Paul)

Never known the failure of a waxstat, and they all fail eventually, to affect cold start at all. You will need to look elsewhere. Your first stop should be air leaks on the input side.
